To all whom it may'concem 1 i Be it known that-I, GEORGE1.A. Bornn, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of'California, have invented new and useful Improvements in Splash. OilingSystems, of which the following is a specification. .1 a

This invention-"is a splash oiling system arranged 'to convey the lubricant splashed by a rotating member back'to thecasing of the machine of which the rotating. member is a part. More specifically the invention is particularly applicable to an .i1iternal combustionengine wherein the lubricant in the crank case is splashed by the fly wheel of the engine, the. improved: system contemplating the employment of means foruconveying the lubricant splashed up by the fly wheel back to'the opposite end .ofthepcrank case of the engine." 1' a collecting the lubricant,

"It is the object. of the invention to provide an improved system of thisicharacte'r in which the'means for collecting the lubricant splashed bythe-fly wheel'is .formed as an integral part of the usualengine frame construction, this lubrica'nt collector being connected by arconduittwithaIusual port formed in theic'rank case of the engine, and said conduit being,'.:preferably,1 provided with a sight feed for indicating the proper working of the system. V

The invention will be readily understood from the followingdescription of the accompanying drawings, in which--- 7 Figure 1 is a perspective view'of a portion of an engine frame showing the means for Fig. 2 is a side elevatlon, partly in vertical section, of an internal combustion engine having the improved oiling system associated therewith.

Fig. 3 is a side elevation of the portion of the engine frame embodying the lubricant collecting means. I I

Fig. 4: is a bottom plan view of the same, partly broken away.

The improved oiling system is employed in connection with an internal combustion engine having the usual crankcase 1, the rear continuation of which shown at 2' is arranged to receive the fly wheel 3- 0f the engine. The casing 2, as in the usual construction, is provided with a top closure plate 4 arranged adjacent to and in rear of j the fly wheel 3. In my improved oiling sys Specification of Letters Patent.

der side with a lubricant collecting chamber arranged to receive the. lubricant splashed A E FHCEZ jtem this closure plate is provided itsun chambers is provided at'the'underside of plate l,:sa1d chamber, preferably, extendng lengthwise of said plate-and gradually increasing in depth from'a point5 toward the endof said chamber which is adjacent thefiy'wheel. The portion of -the'chamber extending in 'the opposite direction along the plate 4 from the point 5 is, preferably,

of the same depth throughout to form the reservoir 6. The forward endof'chamber 5',

preferably, turns at substantially right angles to the longitudinallyextending por tion of said chamber as shown at .7', said turn in thelubricant collecting chamber bemg toward the direction of rotation of the fly wheel. This end portion of-the collecting chamber is, preferably, arranged above and in rear: of thefly wheel, as clearly shown in Fig. 2, and the front 'end of said chamber .15 open as shown atfS, and'theside of'said chamber adjacent fly' wheel-3 is, preferably,

also. open at the' upper portion thereof as shown at 9; A'scireefilO extends *across'the collecting chamber, preferably, at the jam tion' of the" angularly disposed end .7 and the longitudinally extending portion 5 said chamber.

A pipe 11 communicates with. the chamber 5, preferably, through a port 12 formed in plate 4, this pipe extending laterally fromthe plate 4 as shown in Fig. 1. The

port l2 is, preferably, arranged in the oil collecting chamber adjacent the junction of the reservoir 6 with the forward portion of chamber!) which is of gradually'increasing depth. The pipe 11 is connected with a pipe 13 extending forwardly along the engine, preferably, adjacent the lower part thereof, and this pipe is shown as com bolts received ina usual opening 16 at the municating with a sight feed chamber 14 I bottom of the crank case for connecting the upper and lower portions of the crank case may be removed and the pipe 15 may be threaded into this usual bolt opening.

In operation the oil splashed up by the fly wheel will be thrown by centrifugal force into the open end of the collecting chamber through both the open front end 8 of the angularly disposed portion 7 of said chamber and also over the wall 9 at the side of said portion of the chamber which is adjacent the fly wheel and which terminates at its upper end in the opening 9. The oil thus collected in the portion 7 of the collecting chamber will flow therefrom into the main portion of the collecting chamber through the screen 10, the gradually reduced depth of the collecting chamber bringing all of the lubricant thus collected at the enlarged end of the chamber toward the plate 4 so that it may be readily discharged from the collecting chamber through the port in plate 4 cominunicating'with pipe 11. The reservoir 6 in rear of the discharge port 12 will be filled with the oil thus collected and will assist in maintaining a steady flow of oil from the collecting chamber into pipe 11 during operation of the system. The oil flowing into pipe 11 will be returned through the sight feed '14: where the condition of operation of the system may be observed, and from thence the oil will be returned to the forward end of the crank case through the pipe 15.

Thus it will be seen that I have provided an eflicient splash oiling system for an internal combustion engine in which the parts are of few and simplified construction and the collecting chamber for the system made as a portion of a usual part of the crank case.

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is: 1. A splash oiling system for a casing having a fly wheel t erein, said casing hav- 7 ing a cover plate comprising a collecting chamber upon the under side of said cover plate, said collecting chamber extending lengthwise of said plate and having its forward end angularly disposed relative thereto and projecting in the reverse direction to the direction of rotation of the fly wheel, and a screen across said collecting chamber at the forward angularly disposed end thereof.

2. A splash oiling system for a casing having a fly wheel therein, said casing having a cover plate comprising a collecting chamber upon the under side of said cover plate, said collecting chamber extending lengthwise of said plate and having its forward end angularly disposed relative thereto and projecting in the reverse direction to the direction of rotation of the fly wheel, said collecting chamber increasing in depth toward said forward angularly disposed end.

3. A splash oiling system for a casing having a fly wheel therein, said casing having a cover plate comprising a collecting chamber upon the under side of said cover plate, said collecting chamber extending lengthwise of said plate and having its forward end angularly disposed relative thereto and rojecting in the reverse direction to the irection of rotation of the fly wheel, the end of said angularly disposed end of the collecting chamber and the side thereof adjacent said fly wheel being open.

In testimony whereof I have signed my name to this specification. I
